<body class='hmmessage'><div dir='ltr'>Hi Tobias,<div><br></div><div>As there is no standard "dns" suffix, I just added a .cloud to the hostname. </div><div>You can change it by doing the following:</div><div><br></div><div>- Edit /usr/lib/one/ruby/cloud/metadata/MetadataServer.rb</div><div>- And replace .cloud with your domain:</div><div><span style="font-size: 12pt;"> when 'local-hostname' # 2007-01-19</span></div><div><div> @value = "i-#{vm.id}.cloud"</div><div> when 'public-hostname'</div><div> @value = "i-#{vm.id}.cloud"</div><div><br></div><div><span style="font-size: 12pt;">If you use the econe-* commands, userdata and public key should work without any change.</span></div><div>If you create your own template, just add the following to context:</div><div><br></div><div><span style="font-size: 12pt;"> CONTEXT = [</span></div><div><div><span style="font-size: 12pt;"> (...)</span></div><div><span style="font-size: 12pt;"> EC2_USER_DATA = <YOUR USER DATA></span></div><div> EC2_PUBLIC_KEY = <YOUR PUBLIC KEY></div><div> EC2_KEYNAME = <THE NAME OF THE KEY></div><div> ]</div></div><div><br></div><div>If you want to use your own variables instead, just change them on /usr/lib/one/ruby/cloud/metadata/MetadataServer.rb.</div><div><span style="font-size: 12pt;">Search and replace with your own data:</span></div><div><br></div><div> TEMPLATE/CONTEXT/EC2_KEYNAME</div><div> TEMPLATE/CONTEXT/EC2_PUBLIC_KEY</div><div> TEMPLATE/CONTEXT/EC2_USER_DATA</div><div><br></div><div>The metadata server was thought to work with instances launched by eucatools, hybridfox or econe-* , and assumes that you are using the standard /etc/one/ec2query_templates/*.erb .</div><div>But it can be easily modified to be more generic.</div><div><br></div><div>Regards,</div><div>Ricardo Duarte</div><div><br></div><div><div>---<span style="font-size: 12pt;">---</span><span style="font-size: 12pt;">---</span><span
